Due to its special structural composition, silane has gradually become an indispensable component of coating and ink systems. Either as an additive or as a primer for coating alone, it will give excellent performance to coatings and inks. The consequences of not adding silane correctly are that the coating cannot be kept for a long time and the storage period is extremely short.

In the case of acrylate coatings, for example, copolymerization of acrylic acid and styrene monomers with Co-Formula silane coupling agents results in the synthesis of Co-Formula silane coupling agent-based acrylate emulsions, which can be made into room temperature cross-cured acrylate coatings. A typical addition of a silane coupling agent to a coating is to polymerize only a small portion of the copolymerized monomer premix in a reactor and then slowly add the remainder from a buffer tank.

Typical steps are as follows.

1. Add water, surfactant and retarder to the reactor. 
2. Add 5%-10% of copolymer monomer premix (without silane coupling agent) to the reactor.
3. Heat the above mixture to the best temperature that the manufacturer has, the typical temperature control is about 65℃-75℃. 
4. Add all catalysts and initiators to the reactor. 
5. Control the rate of addition of the remaining copolymer monomer premix to the reactor, with a typical time range of 4-6 hours. 
6. Add additional silane coupling agent to the buffer tank when 10% of the copolymer monomer premix remains. Mix the silane coupling agent and the remaining 10% of the copolymer monomer premix completely and continue adding to the reactor at a controlled rate. 
7. After adding the copolymer monomer premix, maintain it for a sufficient time to obtain the maximum degree of polymerization.
