Solids solvent-addition silicone releaseagent is generally 30%. When diluted with toluene, n-hexane, etc. to a solidcontent of 2% to 10%, dubbed a catalyst coating liquid. To minimize the amountof solvent can also be formulated as solids content of the coating liquid 10%to 30%. Concentration or viscosity of the coating liquid to the substratewettability, curing and the use of others have subtle effects. It is generallythe concentration should be specified merchandise conditions to prepare acoating solution.
Low concentrations of the coating solutionafter adding the catalyst using a long period. But too much diluted, becausethey have a resistance to the substrate surface. Concentration of the coatingsolution is generally not less than 5%.
High concentrations of silicone dilutedwith a solvent dubbed the coating liquid, the substrate surface withoutexcluded its type, can be very thin coating layer. In addition, the excludedtype also have a certain relationship with the type of the solvent. Aromaticsolvents excluded prone to resistance, aliphatic hydrocarbon solvents lessprone excluded sex.
