Water-resistant clear resin

A moisture-resistant, nearly colorless clear resin; flow tests and lens prototypes.

What is Water-resistant clear resin?

Resins in this class (the best known being Somos WaterShed XC 11122) offer mechanical properties close to ABS and PBT and absorb very little water or moisture. Thanks to their nearly colorless clarity, they are used for flow visualization models, prototypes that carry liquids, lenses and light guides.

Frequently asked questions about Water-resistant clear resin

What is Water-resistant clear resin?

Resins in this class (the best known being Somos WaterShed XC 11122) offer mechanical properties close to ABS and PBT and absorb very little water or moisture. Thanks to their nearly colorless clarity, they are used for flow visualization models, prototypes that carry liquids, lenses and light guides.

Is Water-resistant clear resin heat resistant?

The heat deflection temperature (0.45 MPa) of Water-resistant clear resin is about 50 °C. This is low; it is not suitable for hot car interiors, direct sun or hot water.

Can Water-resistant clear resin be used outdoors?

It can degrade under prolonged sunlight and UV light. For outdoor use, ASA or another UV-resistant material should be preferred.

Which parts are made with Water-resistant clear resin?

Water-resistant clear resin is typically used in applications such as flow visualization models, prototypes carrying liquids, lens and light guide prototypes.

Which material can be used instead of Water-resistant clear resin?

Depending on the application, Clear resin, PC, PETG can be alternatives. You can see the differences in the comparison tables on the material pages.
