C.Adhesive field
1.Aldehyde & ketone resin is suitable for cellulose nitrate adhesive used in bonding of textiles, leather, paper and other material.
2.Aldehyde & ketone resin is applied in hot melting compound with butyl acetoacetic cellulose due to excellent heat stability to control melt viscosity and hardness of cooling block.
3.Aldehyde & ketone resin is soluble in ethyl alcohol and is with certain hardness. It is suitable for manufacturing of polishing agent and wood surface treating agent.
4.Aldehyde & ketone resin is used as textile water-proofing agent in cleaning.
5.Aldehyde & ketone resin is used in polyurethane component adhesive to improve adhesion fastness, brightness, water proofing property and weather fastness.
