Silicone defoamers are also limited by their use of environmental conditions -- 2017-08-24

Selection and use of silicone defoamersshould pay attention to the problemAnd other non-silicone defoamers assilicone defoamers are also subject to restrictions on the use of environmentalconditions. Binding conditions and different defoamer performance liveenvironment to determine the appropriate species. When necessary, it isdesirable foaming liquid sample to simulate the actual conditions of use anddefoaming experiments to determine the amount of anti-foaming agent.In actual use, the bubbling ...

Polyethylene, polypropylene, polyvinyl chloride and other film anti-sticking treatment -- 2017-08-23

UV-curable silicone releasing agentUV-curable anti-blocking agent is fasterthan the above heat-curable anti-adhesive curing speed. And in principle, withheating, ideal for low heat resistance of the substrate. As release-treatedpolyethylene, polypropylene, polyvinyl chloride film. UV-curable siliconereleasing agent and by product form can be divided into solvent-free andsolvent-based. The latter is mainly used for coating film thickness of 0.5μm orless. Press the curing reaction by type, mainly ...
