Chemicals

These are representative of the chemical products from H.E.C. Group.
Focusing on adhesives for industrial use, they are currently used by a wide range of industries.

Adhesives

Adhesive toughening agent, surface preparation agent with a polyurethane and natural rubber or synthetic rubber base. An environmentally friendly product that replaces methyl chloride with ethyl acetate. It has a high concentration of polyisocyanate for reinforcing effect, and shows a greater environmental compatibility. Its main use is industrial, such as a rubber adhesive for shoes.

Components

A trithiophospolic acid (P-isocyanatephenylester), ethyl acetate.

Appearance

Clear, brownish yellow, yellow-green, reddish brown, deep purple liquid

Physical properties

Solid content	About 16％
Content	4.5％
Viscosity	About 3.0
Vapor density	1.0g／cm³
Vapor pressure	97mba (20°C)
Flash point	－4°C
Odor	Like an ester

Usage

When the adhesive materials are mixed, the adhesive effect appears shortly regardless of resins, preservatives or other solvents. After opening, the period of time for adhesion is 1-2 hours, and the longer the length of open time, adhesive effect or power will decrease until it hardens.

Dissolution Method

It can be thinned with water, acetone, non-alcohol methyl acetate, ethyl acetate, methyl ethyl kentone, toluene, etc.

Container

Aluminum bottle holding 750g or a drum containing 55kg

Storage

Store tightly as a rule. As it reacts easily with water, take care not to mix the container with water or moisture. In the case of the expedited shipping drum, it is better not to dispense bit by bit, but to store usable amounts in aluminum or glass bottles.
The containers should be tightly closed with polyethylene screw caps. Those made with alkaline components cannot be used. Since denaturing could occur in transparent containers due to heat from light, care is required about heat (40°C or higher) particularly in summer.
