Recommended dosage: 1-2% of resin solids.
These lubricants (slip agents) and anti-scratch agents, in addition to lubrication (slip) and anti-scratch applications, are also used in gloss enhancement, extinction, leveling and texture.
Antistatic agent, charging agent and friction charging agent
Antistatic agent is an auxiliary agent that uses the characteristics of surfactants to absorb moisture in the air, polarize the surfactants, form a very thin conductive layer, and generate static leakage channels. The widely used antistatic agent is a surfactant, which leaks charges or reduces the coefficient of friction through different methods, thereby inhibiting the generation of static electricity, reducing the surface resistance of the coating film-forming material, and accelerating the leakage of electrostatic charges. In a typical antistatic agent surfactant molecule, one end of the two end groups has a hydrophilic group (X) and the other end has a lipophilic group (Y), forming an XR-Y structure, and has an appropriate hydrophilic affinity. Oil value (HLB). In the molecular structure of the antistatic agent, the proper matching of the hydrophilic group and the lipophilic group has a great influence on the antistatic effect. Among the lipophilic and hydrophilic groups of antistatic agents, the hydrophilic groups can be divided into slightly hydrophilic groups,
General hydrophilic group, strong hydrophilic group, etc. The lipophilic groups are H, C<-CH:) .. C, Hs one, Ce Hu one, Ca Ha-, (CH, CH, CH:) ., (CH:); Si(CH:, CHa《CH :,
<CHy-CHO X, etc.; slightly hydrophilic groups have CHg-O-CH, CHOCH, *-COOCH g, -CS, -CSS H, -CHO, -NO, etc.; general hydrophilic groups have OH, -COOH, -CN, -NC·CON He, CON H, -CO OR, OSO, N, etc.; strong hydrophilic groups include -G HIS OH, -SO.H(-SO, Na), -COON a, -COON He, Cl, -Br, -1, etc.
Antistatic agents can be classified according to their chemical structure. Generally, they can be divided into cationic, anionic, nonionic and amphoteric types. Commonly used antistatic agents are these four compounds or complexes.
