Description

Tough-Cast Polyurethane Casting Resin

Tough-Cast 65Dis an incredibly strong and durable 1:1 ratio two-component semi-rigid polyurethane casting resin. It features excellent impact resistance, abrasion resistance, strength, and high heat deflection.

Tough-Cast 65D is virtually indestructable and is the best casting resin for semi-rigid durable plastic prototyping. It has has the look and feel of thermoplastics such as abs while maintaining a high heat deflection.

With a 2-minute work and 30-minute cure time, Tough-Cast 65D contains zero solvents and can be hand-mixed or used with automated dispensing equipment. Tough-Cast 65D works well with resin casting molds created with RTV silicone.

Tough-Cast 65D Common Uses:

  • Prototype Parts
  • Reproductions
  • End-Use Production Parts
  • Industrial Parts
  • Rollers

Tough-Cast 75D vs Tough-Cast 65D :

Both Tough-Cast 75D and Tough-Cast 65D have excellent strength, durability, and impact resistance. Choosing the right one for the job depends on the application and properties you are looking for in your finished part.

Tough-Cast 75D is ideal for applications where you need both toughness and stiffness. It has a lower viscosity than 65D, making it the ideal choice for finer more detailed molds. 75D has a longer working time than 65D and is also virtually odorless. For example, Tough-Cast 75D is a smart choice for a highly detailed, impact resistant prototype. Tough-Cast 75D is comparable to Smooth-on TASK™ 9 high performance casting resin.

Tough-Cast 65D is ideal for applications where you need a small amount of flexibility as well as more abrasion resistance. It also has a higher heat deflection than 75D. For example, Tough-Cast 65D is a smart choice for knuckle guards on a dirt bike. Tough-Cast 65D is comparable to Smooth-on Smooth-Cast™ 65D semi-rigid urethane casting resin

Frequently Asked Questions

What happens to resin if it has passed its shelf life?

When a product has exceeded its shelf life, the casting process can become unstable. Working time and demolding time will likely change as well.

Does temperature play a role in the casting process?

Temperature plays a major role when it comes to mixing and curing silicone, resin or epoxy. Heat and humidity can speed up your curing time and cooler temperatures will do the opposite and slow down your curing time.

How much metallic or glow-in-the-dark powder am I supposed to use in my resin or epoxy project?

When adding metallic or glow-in-the-dark powder to your resin, you should start by adding small amounts and continue to add more until you reach the desired result.

What is the right amount of pigment to use?

When adding pigment to a project remember a little goes a long way. Add pigment by drops until you reach the desired color. Make sure to make a note of how much pigment you used so you can match if making multiple batches.

How do I eliminate bubbles in my silicone mold?

There are few ways you can eliminate bubbles in your silicone rubber mold:

  • Degas material within the working time frame.
  • Pour a thin stream and allow material to slowly fill in any negative space.
  • Use a thinning agent that will allow bubbles to rise faster.

Works great and dries very quick

Great Product (if you’re quick)

Easy to work with and is the perfect durometer for what I needed, but the working time seems a lot faster than 2 minutes and I even tried working in cooler temps. I’ll probably try something with a bit more working time in the future.

Very impressed with how easy it was to use this product. Simply mixed it 1:1 and then poured it in my mold. Doesn't get easier than that.
