Cashew Friction Dust is a common and important ingredient of friction linings formulations. Friction Dust represents up to 20% by weight of friction elements used in manufacturing of brake lining, brake pads, brakes shoes, railway block and clutch facings where high absorption and frictional properties are needed
Applications
| GP001: Black particle with improved hardness and heat resistance for disc pad applications. | GP002: Brown particle with good heat resistance used for all normal to heavy duty disc pad and drum lining applications. | GP003: Extra Fine brown particle with improved hardness and higher heat resistance for disc pad, clutch facings and friction paper applications. |
| GP004: Fine Brown particle with good heat resistance used for Brake linings and Clutch Facings. | GP005: Black particle effective in improving brake feel, reducing noise, and increasing high temperature stability. Appropriate for Brake Linings and high-end brake applications used for Heavy Duty. | GP006: Extra fine Brown particle with higher heat resistance used for Clutch Facings. |

These are a unique type of hardeners that possess the rapid curing characteristics of the aliphatic polyamines while also exhibiting the non-volatility and low order of toxicity associated with polyamides.
The Mannich reaction of Cardanol, formaldehyde, and certain amines is called a Phenalkamine. Phenalkamines share some similar advantages to other Mannich base curing agents, such as: extremely fast cure, low temperature cure (even below 0C), good chemical resistance, good surface appearance, good moisture tolerance, and non-blushing properties. However, due to the long aliphatic side chain of Cardanol, Phenalkamines also have very good pot life, good flexibility, surface tolerance, and excellent water and salt water resistance.
Our company offers large range of phenalkamine curing agents, phenalkamine adducts, reactive diluents and Epoxy resin modifiers for civil and coating applications.
GCPPL believes in harnessing the power of technology to deliver products that score high on the quality quotient. We have an array of cutting-edge machinery that manufactures products in its state-of-the-art unit. The manufactured products are then subjected to rigorous quality checks at its advanced QC department. The end-result is a range of products that ensures total satisfaction for the customers. We have a full-fledged Research and Development wing that continuously develops new products and enhances the existing ones for better performance.
GCPPL Phenalkamines constitute a new class of low temp. curing agents. The unique chemistry creates a new route of improving a system by chemical modification of structure.
We offer a wide range of epoxy curing agents, diluents, and resins derived from natural cardanol that are designed especially to address the needs of various heavy duty coating applications. Specialized technical resources are devoted to understanding the existing problems of heavy-duty coatings, and products are tuned to make sure these problems are addressed. By using tools designed for a specific target application, formulators can develop products more rapidly and deliver better solutions for their customers.
The advantages that result from these chemical changes have important application in many branches of industrial maintenance and maritime industries.
Some important features of our Phenalkamine curing agents are:
