Gelcoat Resin

Gelcoat Resin Intro

Gelcoat Resin Intro

Gelcoat resin is a specialized material used to provide a high-quality finish to the visible surfaces of fiber-reinforced composites. It is commonly used in industries such as marine, automotive, and recreational vehicles.

TM48 is a fire-retardant gelcoat made from isophthalic unsaturated polyester resin. It offers excellent flame resistance (high oxygen index, low smoke density), good mechanical and application properties, and water resistance. It is ideal for lifeboats, train parts, and other FRP products, and can be applied by spraying or hand layup.

TMP321 is an Iso-NPG type gelcoat used for manufacturing large flat laminates such as coach composite sheeting and big table panels. It features excellent mechanical properties (high flexural strength, impact strength, and high elongation), good processing properties (good leveling, no drainage, versatile processing suitability), high glossiness, good weather resistance, and high toughness. It is suitable for different processing technologies.

Hand laid up truck cover

TM S301 is an Iso-NPG type polyester gelcoat, while TM S201 is an Iso type polyester gelcoat. Both are sanding gelcoats with good mechanical and application properties. Their surfaces are easy to sand and stick well with surface paint. They are ideal for FRP products that require a polished surface and can be applied by spraying or hand layup.

TM86 is a vinyl ester type gelcoat with high properties, including high hardness, high luster, impact resistance, weather reliability, rub resistance, and good toughness. It is used in FRP molds and the manufacture of other FRP products. It can be applied by spraying or hand layup.

Components (3)

Usage Steps (5)

  • Surface Preparation

    Clean the workspace and the surface to be coated with acetone to remove debris and contaminants.

  • MEKP

    Mix the gelcoat with a catalyst (typically MEKP) to initiate curing. The ratio of catalyst to resin is crucial for proper curing.

  • application time

    Apply the gelcoat in multiple layers, allowing each layer to set before applying the next. The total thickness should be around 20-25 mils.

  • Curing

    Allow the gelcoat to cure properly, which can be influenced by temperature, humidity, and catalyst concentration.

  • surface polishing

    After curing, the surface may need to be sanded and polished to achieve a smooth, glossy finish.

Functions (4)

  • Provides a smooth, glossy surface that often requires no additional painting in many applications.

  • Available in various colors, with pigments added to achieve the desired hue.

  • Acts as a protective layer for the underlying fiberglass or composite materials, preventing water absorption and resisting UV radiation.

  • Facilitates the separation of the finished product from the mold after curing.
