Pukhraj Engineering & Chemicals Private Limited

We manufacture and supply a wide range of anti tack agents which find their applications in various applications in the rubber industry. Our anti tack agents are processed through proper process to retain the requisite advantages for the rubber processing.

Our range comprises of the following:

(1) STUCK-N:

The stuck-N agent does not contain any petroleum/bituminous oil. This agent is formulated through the celluloid preparation of salt of oleic acids mixed with fillers & amides. Available in pale white free flowing liquid stuck-N is used as an anti tack agent for uncured rubber sheets of mixed compounds. It helps preventing sticking of compounded sheets, semi finished goods and extruded articles to each other.

Specifications:

• Appearance: Pale White free flowing liquid.
• pH value:9 - 10
• Solid Content: 25 ±2 %
                        : 30 ±2 %
                        : 40 ±2 %
  

Application process:

Stuck-N should be used in diluted form which is possible by mixing water till the desired level of concentration. The aqueous solution is used for spraying, brushing and dipping.

Dosage:

For soft compounds like sponge compound sheets concentration of 1 part by weight Struck N in 5 parts by weight of water can be used. Extruded hoses can be dipped in an aqueous solution of 1 part by weight of Struck N in 3 to 6 part by weight of water.
