0.3%-1.0% is recommended to be added to interior wall coatings.

In special applications, the exact amount to be added will be tested by our microbiology laboratory.

 

 

 

 

 

 

 

 

 

 

 

 

 

This theory can explain the fact that the chemical bonding theory cannot explain: some silane coupling agents that cannot react with the resin have a good coupling effect on some resins, but have no effect on other resins. For example, (MeO) sSi CsH, CI cannot react with epoxy resin, but it has a good coupling effect on epoxy glass fiber reinforced plastic. The reason is: because the critical surface tension (42.5mN/m) of the (MeO) aS iCg HgCl film formed on the glass cloth is greater than that of the epoxy resin x (38~40mN/m), montan wax uses so by (MeO): SiC aH. Cl-treated glass cloth is easily wetted by epoxy resin.

Constraint Layer Theory
Ga eh de [1 studied the effect of three kinds of silane coupling agent modified kaolin fillers on the reinforcement of high-density polyethylene (see Table 167). Vinyl silane can be grafted with polyethylene, while methacrylate silane is only used in Homopolymerization in the interface zone, and has a better effect on improving the crystallinity of polyethylene at the interface. In addition, methyl lactoate silane and aminoalkyl silane will form an interpenetrating polymer network with polyolefin at the interface. Although vinyl silane can chemically react with polyethylene, it is the least effective of the three coupling agents mentioned above. Therefore, the mechanical properties of polyethylene filled with kaolin are not so much related to chemical bonding and grafting, as it is to the structure of the interface polymer.

The effect of kaolin (on pottery) treated with silane coupling agent on the reinforcement of high-density polyethylene
The constrained layer theory proposes that the resin in the area of ​​the inorganic filler should have a modulus between the inorganic filler and the matrix resin. Therefore, the constrained layer theory believes that the function of the silane coupling agent is to “tighten” the polymer structure in the interphase. From the performance of the reinforced composite material, if you want to obtain the maximum adhesion and hydrolysis resistance, you need a constraining layer at the interface.
