Unsaturated Polyester Resins

Unsaturated polyester resins (including vinyl esters and additives) are used in the production of fiber reinforced plastics or non-reinforced filled products. Due to the ease and freedom of processing, you can apply these unsaturated polyester resins during the manufacturing stage itself to both small and large structures. Used mainly in the Chemical Process Industries they find common application in:
•    Marine (gel coats)
•    Automotive
•    Wind Turbine blades
•    Electronics
These resins have the following characteristics:
•    Excellent chemical resistance
•    Low Shrinkage
•    Excellent wetting and bonding to glass fibers

We are engaged in offering a wide range of Orthophthalic based resin popularly known as General Purpose Resin which is an economical choice for hand lay-up process, spray-up, roofing, general fiberglass repair, wood boat construction and repair and gel coat blister repair etc. This range has excellent pot life and cure-time control.
Applications:
•    Useful for manufacturing water tanks
•    Automotive parts
•    Marine parts
•    Modular cabinets
•    Used extensively for general FRP applications
•    Used for moderate environments and Water Corrosion resistance
Some of the salient features of our products are:
•    Non-saturation
•    Quick remolding capacity
•    Medium reactivity
•    Good wet-out properties

We specialize in manufacturing Isophthalic Resins, which finds vast application in manufacturing tanks, containers, pipes, tooling, storage for corrosive materials and other products that require high mechanical strength, corrosion resistance and durability. It is suitable for both hand lay-up and spray-up processes.

Our range of products is gaining immense popularity in industrial and composite sectors for the features:
•    Hydrolytic stability
•    Non-saturation
•    High strength retention
•    Chemical resistance
•    High Acid Resistance
•    Higher Mechanical Strength of Laminates
•    Good electrical properties

We are one of the leading manufacturers of Buttons Resins specifically used in manufacturing buttons with centrifugal casting method. Our range is made of orthopthalic based and medium reactivity resins. The specialty of these resins is clear castings that enable the coloring of buttons with pigment pastes to obtain the best color. Our clients can also procure from us water white resins that are used for manufacturing small gift items.
Some characteristics of our range of products are:
•    Flexibility,
•    High viscosity,
•    Optimized curing

We are preferred glycol manufacturers for high-performance unsaturated polyester resins (UPR) for many thermoset composite applications. Propylene Glycol Industrial Grade (PGI) is an excellent choice for these applications. For applications that require more flexible or hydrolytically stable resins, dipropylene glycol is used.        

Common UPR application areas include:
•    Reinforced plastic laminates for marine construction, bath ware and shower stalls
•    Electrical components
•    Pipes
•    Tanks
•    Ducts
•    Sheet molding compounds (SMC) for the automobile and transportation industries
Non-reinforced thermoset applications include:
•    Gel coats
•    Buttons
•    Synthetic marble castings

Gelcoat is the specialty product/branded trademark product of unsaturated polyester resin process at Renaissance Expo International. These resins are tailor made to meet the diverse needs of GRP/FRP industry for meeting the requirements of customer’s interest of improved efficiency and superior performance of finished products. These usually have the following applications:
•    Used for giving a smooth top coat to FRP articles.
•    Used for imparting surface color, elasticity and gloss.

Epoxy or poly epoxide is a thermosetting polymer formed from reaction of an epoxide "resin" with polyamine "hardener". Epoxy has a wide range of applications, including fiber-reinforced plastic materials and general-purpose adhesives.
Epoxy is a copolymer; formed from two different chemicals referred to as the "resin" and the "hardener". The resin consists of monomers or short chain polymers with an epoxide group at either end. Most common epoxy resins are produced from a reaction between epichlorohydrin and Bisphenol-A, though the latter may be replaced by similar chemicals. The hardener consists of polyamine monomers, for example Triethylenetetramine (TETA). When these compounds are mixed together, the amine groups react with the epoxide groups to form a covalent bond. Each NH group can react with an epoxide group, so that the resulting polymer is heavily cross-linked, and is thus rigid and strong.
The process of polymerization called "curing" can be controlled through temperature and choice of resin and hardener compounds; the process can take minutes to hours. Some formulations benefit from heating during the cure period, whereas others simply require time, and ambient temperatures
The Bisphenol Unsaturated Polyester Resin has excellent corrosion resistance to acids, mild alkalis, salts and solvents. They find wide application in the following areas:
•    Chemical process plants
•    Acid resistance Pipes
•    Acid Storage vessels
