Surfboard

Silmar® brand SIL66 resins are the most widely used resin for surfboard manufacturing and hand laminating in the industry. In fact, they are sold throughout the world. These resins feature low color (almost water clear) and excellent UV-resistance (UV-stabilized). They have remarkable stability for consistent viscosity and excellent wet out and gel times. All contain Silmar’s proprietary promoter package designed for surfboard production and room temperature cure.

Our SIL66BQ-249A has been the best-selling surfboard resin in the world with a sales volume that exceeds all other resin competitors combined. In 1961, in Hawthorne, California the Beach Boys developed their unique and lasting Surfing sound. The unique and lasting quality of our SIL66BQ-249A was also developed in Hawthorne, California, that same year, at the Silmar® facility where Interplastic continues to make the SIL66 family of resins. In 2021, Interplastic celebrates the 60th Anniversary of the Silmar® brand resins, still the best-selling resin for traditional surfboards.

The SIL66 product range consists of:

  • the original 249 family
  • the alternate 250 versions that contain wax
  • the newest, 2880 family, which features an acrylic modified formulation.

This resin, released in 2014, is enhanced via an acrylic-modified polyester formulation. This resin has better UV-resistance than other surfboard resins, is tougher, and has improved impact resistance to reduce stress and deck cracks.
