2. How long does GRASi product last?

In 2005, GRASi commissioned the school of materials science and engineering of Tongji University in Shanghai to carry out the research on the production performance of acid rain resistant and chlorine ion protective agent products produced by GRASi. Conclusions are as follows:

The use of GRASi acid rain resistance and anti chloride ion protective agent concrete substrate, in acid rain and chloride ion erosion environment which can effectively improve the concrete anti chloride ion penetration and acid rain resistance ability. In chloride corrosion and acid rain environments, the strength of the concrete protected by GRASi does not change, and the volume & weight do not change.

Predictions obtained in this model study show that GRASi acid rain resistant chloride protective agents are applied to concrete to protect its life span for more than 10 years.

3. How many years of market experience of GRASi? Annual production capacity?

GRASi is an international company which started to develop,production,sell protective agent in 2002. We have professional market application, development and sales experience. We aim to be the world protective agent company. Our products are devided into 9 categories. The current annual capacity of GRASi is 10000 tons, constantly increasing.

4. If compare with Euro and USA similar products,what are the advantages of GRASi?

For different substrates and different requirements, GRASi develops new products,like nano penetration protection and nano coating, such as the corrosion protection concrete coated with GRASi products, can be placed in sulfuric acid solution soak for 16 hours, the test will not change the compressive strength of concrete, receive highly recognized by customers in Europe and the United states ,for vehicle surface protection ,effect is unique, waterproof, smoothness is the leading among competitors in Europe and the United states.

5. Are GRASi products safe, non toxic and breathable?

GRASi protective agent are safe.non toxic and breathable. Different protective agent will suitable for different substrates, not only do not damage material, but also are able to improve the lifespan of substrate and achieve the best effect. After coated, GRASi products are transparent, odorless, breathable and comfortable if compare with similar products.

6. Any differences between GRASi salt protection and carbonation protection?

GRASi anti chloride ion products are for environment of marine and snowmelt. GRASi anti carbonation & rain products are for the environment of acid rain and atmospheric carbon dioxide.

7. Will your company consider set up a warehouse in the main area?

GRASi support our partners to set up a warehouse in the local area which can make the final customers quickly using GRASi products. We suggest that should not purchase too much types and quantities from the beginning. It’s good for keeping the warehouse turnover. If your business has certain scale in the future, we can get further discussion about the plan of how to expand.

8. GRASi products have access to the European market conditions?

Mass purchasing of GRASi products have the capability of REACH filing. Grasi product itself is environmentally friendly, small quantities of products into Europe do not need to apply for the record and certification.

9. How to improve the corrosion resistance of concrete?

Concrete corrosion is caused by water seepage, water erosion, concrete containing various types of acid alkali and salt, and the summer of UV irradiation and frost damage will accelerate the aging of concrete, GRASi protective agent not only waterproof effect, resist acid rain, chloride ion, anti alkali, anti freezing and thawing,anti UV effect, effectively improve the durability of concrete.

10. What are the advantages of GRASi products if compare with similar products?

For GRASi products can be combined with the substrate completely without membrane on substrate when finish treated. It’s also breathable. But for coating materials can not breath,as membrane will peel off after a period time treated.

11. Applying GRASi products, but not show water beading effective on the surface what is poor quality?

If coated with GRASi products for a period time or a long time, the product will not appear surface mounted water is normal performance. Because of dust or contaminants accumulated on the substrate surface which caused the surface tension changes. It seems that surface can not hold water, but this does not affect the penetration protection layer on the substrate. GRASi product has strong penetration into inner layer. Water beading is not equal to waterproof effect. For example, GRASi WP1319, it has excellent anti acid rain and anti chloride, but contact angle is very ordinary.

12. Do GRASi product can be mixed with pigment?

Some products can be mixed with the pigment, for the specific needs can consult GRASi professional engineer.

13.Why fabric&leather coating has shorter durability than building coating?

GRASi is a professional manufacturer of the all kinds protective agent. Has two major characteristics: The durability products and functional products. The durability products are mainly for building material & functional products are for the non-construction material.

Fabric protective agent is a super hydrophobic nano technology functional products, used for immediate excellent anti fouling effect. For example, tablecloth of restaurant need do antifouling protection treatment. Will do a uniform cleaning and disinfection for tablecloth after meal, then do treatment again. At this point, immidiate strong anti fouling effect will be needed, durability is not a major manifestation.

GRASi can recommend all kinds of protective agents according to your requirements, or provide you customize products per requests.

14. Applying GRASi products, any influence on cohesion between stone and cement?

GRASi has a special product which is not only has excellent waterproof effect, but also has good adhesive ability between stone and cement. However, due to the different characteristics of various stone materials and the difference of cement mortar water ash ratio, we recommend that the test in the small area after satisfactory, and then applied in a large area.

15. How to use GRASi waterproof powder?

GRASi waterproof powder is a kind of additives which is mixed into concrete or polymer cement products, mainly used for the process of manufacturing cement products or the process of manufacturing waterproof mortar.

The following is a summary of customer consultation:

Q: I am going to add GRASi powder to the production process of the concrete preform, adding volume 1.6% rows of concrete aggregate?

Answer: Sure. It is a very good proportion, under normal circumstances, the water absorption rate can be reduced by 80-90%, after finish the end of cement concrete curing period, will see excellent waterproof effect.

16 .Any difference between powder and liquid?

Waterproof Liquid is coated with the surface, both products can be used according to the specific environment, waterproof effect of both are all very good. If you can tell us the application of the environment and area. We can help you recommend the most suitable products and application method.
