Product Description
KL-2680AB-50 ,Self adhesive silicone coating serves as heat fast curing sprayable version liquid silicone coating which adheres to the glass and silicone rubber products surface sparing from the use of silicone primers on the glass and silicone rubber products substrates.
Attention
1, The user should make changes based on spraying thickness and weather conditions (Temperature ,humidity).
2,The solvent is suppose to be blended solvent. xylol :Ethyl acetate:Cyclohexanone=80:15:5 or Tolune : Butanone =1: 1. too much water in the solvent will cause rough surfaces of liquid silicone coating.
3,The-ready-to-bond glass substrates should be washed clean till no dusts and oil dirts.
4 ,Check during spraying coating process , control the viscosity of the liquid silicone, make sure enough coating amount and get it cured completedly. 5,The spraying environment counts , It is advisable to adopt dust-free plant for production .Temperature controlled at 25～35℃. Humidity controlled at 25～50%. 6, The mixed liquid silicone must be used up in 6 hours , stop use the material when found viscosity increase or material get hardened
Processing
It is advisable to take KL-2680A and KL-2680B based on solid contents 25% (Weight ratio) KL-2680A:KL- 2680B:Solvent=100:100:200. 1,Take the KL-2680A and KL-2680B based on proportionated weight ratios and add the solvent lots by lots. mix evenly with 20-40 minutes . 2,Spray the mixed liquid silicone evenly on the glass and silicone surfaces.
3,When the spraying thickness is10μm ,bake with 150℃ for 2minutes. The baking time is determined by the baking temperature and spraying thickness. when the spraying thickness is 20μm, baking time should be increased to 3 minutes(Note : Data for reference only, please make change based on specifical situation )
