Feature:
It has the advantages of good strength, small deformation, widen use, convenient transportation, longer storage period;
It has the properties of excellent waterproof, mildew resistance, no pollution, etc., and its adhesive strength is higher than the strength of wood;
It can be adjusted by adding other adhesives and curing agents with a certain proportion to achieve optimization.
Powder synthetic resin has the characteristics of a long storage period, convenient transportation, low free formaldehyde, simple storage condition, and convenient use condition. After more than three decades of development, our powdery synthetic resin products have reached and exceeded the number of domestic and foreign competitors in terms of environmental performance, adhesion, and usability. Furthermore, the company constantly carries on the technical innovation according to the market demand so that the products meet the customer's requirement of constantly improving quality.
From the development trend, the customer's requirement is to improve the performance of synthetic resin, such as improving the adhesion force, waterproofing, weatherability, rapid curing, environmental protection, reasonable cost, easy to use, and so on.
The synthetic resins market has huge application scope and demand but its structural adjustment is urgently needed. The low-grade and poor-performance liquid adhesive will be eliminated, so we should vigorously develop powdery synthetic resins.
