contact wenzhou wenzhou HENKEL adhesive contact and acrylic pressure sensitive adhesive tape, double-sided tape, protection tape, textured paper tape, labels, adhesive tape and tape, etc. Not only on the production, and on the adhesion
and coating properties are improved greatly, suitable for various use adhesive tape products.
In the structure of polyurethane resin part introduce hydrophilic group, the emulsification.
New product development with hot melt adhesive joint lining cloth furniture sealing side is on fabric surface evenly Xu Bu made of hot melt adhesive.
Acetone method: first made high viscosity polymer, plus acetone viscosity reduction, with a hydrophilic monomer, chain extender, join the water under the high speed stirring, through strong shearing action to disperse in water, emulsion after vacuum distillation recycling solvent is made of PU water dispersion system.
The main body of pressure sensitive adhesive composition classification in recent years as the packaging, packaging, office supplies and all kinds of tag demand expands, the demand is becoming more and more big pressure sensitive adhesive.
When used under the high temperature of 260 ℃, glass, organic silicon laminate or copper - should be adopted
Ptfe composite panels.
Sealing and isocyanate method: choose the blocking agent of the right to water sensitive side - isocyanate
NCO groups protected, make its loss of activity, add extender chain agent and crosslinking agent, a total of milk made from latex when used by a certain temperature and special catalyst demasking, generating -
NCO terminal base, chain extender to the preparation of waterborne polyurethane, when using the adhesive lining cloth cut into the required shape and size, to be coated with hot melt adhesive side with other fabric materials (
On the back of the hot-pressing bonding.
Water-based coating glue with water as solvent or polyurethane acrylate resin through specialized emulsification equipment, emulsion.
Its advantage is: many varieties, environmental protection, low prices.
Wenzhou HENKEL adhesive contact relative density (
Freezing point -
433, the glass transition temperature
3. According to the classification of solvent properties of water-soluble and emulsion adhesives with modified below small make up for the detailed introduce you to the exhibition of products sell like hot cakes.
Used by the tool before drying of glue can be used warm water to clean.
Now there are a lot of coating is done with water soluble glue, such as general water soluble PA, water soluble PU and leather adhesive, oil wax feeling, the feeling of color paste and other functional material.
Water soluble with its functional and environmental protection, and the price is low, will be the future direction of coating.
Defect is poor film-forming, washing fastness, PU can't stick hot glue.
Both rigid and flexible printed circuit boards, cannot leave the adhesive.
It lining in the clothing layer, as a skeleton of a garment, simplifies the clothing processing technology and time, make the garment with light, beautiful, comfortable, insurance type, washable, durable effect.
Wenzhou HENKEL adhesive contact low toxicity, LD505600mg/kg, had mild irritation to the skin.
