Product introduction  
     Pergut is a general term for a series of powdered chlorine polymers. In addition to its use in anti-corrosion coatings, Pergut can also be widely used in the adhesive industry.
When added to solvent-based adhesives, Pergut can enhance bond strength; when used as a stand-alone adhesive system, it has a wide range of applications, such as durable adhesives between rubber and metal.

Product grade

*Viscosity and iodine color were measured in 18.5% toluene solution.

  Pergut Product Safety 
    Pergut uses the world's most advanced production equipment to produce in Dormagen, Germany. Its production process is owned by Covestro and is able to control the CCl4 content at polar levels. Because it can control the CCl4 content to less than 0.005%pwb (≤50ppm), Pergut conforms to the trend of world development.
Grades S20 to S90 are mainly added to solvent-based adhesives, while the higher viscosity grades, S130 and S170, are the main raw materials used in metal and rubber adhesives.

Pergut Performance Range
Pergut has excellent acid resistance, alkali resistance, water resistance, and salt resistance.
The Pergut series are soluble in a variety of solvents and compatible with a wide variety of resins and compounds.
In the adhesive industry, it increases resistance to the following environments: ozone, mineral oils, chemical combustion, environmental erosion.

Application in neoprene adhesive system
When used in neoprene adhesive systems, Pergut can increase the original molecular bond strength (increase bond strength), increase their heat resistance, and produce light-colored stable adhesives with resin-free formulations. Widely used in DIY, footwear, furniture markets.
In addition to this application, Pergut can be added during vulcanization conditions where elastomers are to be bonded to metals or other substances. This process produces a durable bond and good resistance to high temperatures and weathering. Because of its good chemical resistance and compatibility with a variety of polymers and resins, Pergut is used in many adhesive systems.

1. High initial strength neoprene contact adhesive
In neoprene adhesives using low-melting resins, adding 5-10 equal parts of Pergut (calculated based on the polymer) can effectively increase the initial strength. In general, a medium viscosity Pergut (eg Pergut S 40 or Pergut S 90) is used. Take the shoe industry as an example. Adding Pergut to the adhesive can shorten the curing time of soles and trimmed edges. Another example is the bonding of plastic films and panels in the furniture industry. Because adding Pergut prevents the plastic film from falling off the edges.

2. Light-colored stable neoprene contact adhesive
The color of the neoprene-based adhesive depends on the resin. In resin-free formulations, the settling time is very short. Especially toluene-free sticking solutions. In this case, the addition of Pergut can extend the standing time, while increasing the initial bond strength. This resin-free adhesive has excellent storage properties.

3. Haojia's cost-benefit ratio of neoprene
The ever-increasing ecological and economic constraints keep the adhesive industry in constant search of the ideal compromise between quality and cost. As we mentioned with neoprene, we can see possibilities - even in toluene-free formulations - to achieve acceptable performance at low cost.

4. Adhesion of rubber and metal
Pergut has long been used to bond all different kinds of elastomers - such as natural rubber NR, isoprene rubber IR, butyl rubber IIR, styrene butadiene rubber SBR, ethylene propylene rubber EPDM, neoprene CR, nitrile rubber NBR Or chlorinated polyethylene rubber CM - to metals such as steel, aluminium, brass, etc. The recommended grades are Pergut S 130 and S 170.
This adhesive can be used in bilayer systems even in monolayer systems - mostly in bilayer systems. This is subject to specification requirements for dynamic resistance and corrosion resistance.
