STS-UVA19
Classification:
Product Description
Product overview
UVA19 is a class of UV curing adhesive with good fluidity and high cohesion, UVA20 has moderate viscosity and thixotropic index, and UVA30 has good base-high capacity, all of which are suitable for temporary masking of local plating, and are resistant to nickel-plating, gold-plating, silver-plating and other plating processes. The viscosity of the colloid has a wide range, which can be selected according to the customer's needs.
- Cured with strong adhesion; at the same time has a high cohesion, suitable fracture elongation, in addition to the glue is not easy to break the gel.
- Suitable for both manual and automatic dispensing.
- Viscosity, thixotropic index and colour can be adjusted as required.
Major application
Temporary masking of localised plating.
