Description

Tough-Cast 75Dis an incredibly strong and durable 1:1 ratio two-component polyurethane casting resin. It features high impact resistance, strength, and chemical resistance.

Tough-Cast 75D is the best casting resin for durable prototyping and precision casting. It contains zero solvents, and the clear amber color makes for easy coloring.

With a 6 to 7-minute work and 60-minute cure time, Tough-Cast 75D can be hand-mixed or used with automated dispensing equipment and works with resin casting molds created with RTV silicone.

Tough-Cast 75D has a low, easy-to-mix viscocity, which ensures minimal bubble entrapment when casting. Cast with confidence with this high-performance urethane casting resin.

The Toughest Resin for the Job:

  • Virtually Indestructible (Will NOT Shatter or Deform)
  • High Impact Resistance & Strength
  • Low Viscosity for Easy Pouring and Mixing
  • Low Odor & Great Chemical Resistance
  • High Detail for Fine & Complex Molds
  • Easy to Color, Easily Pigmented
  • Cost Effective
  • Long Work Time (6-7 minutes)

Tough-Cast 75D Common Uses:

  • Prototype Parts
  • Taxidermy Replicas
  • Models & Figurines
  • Sculptures
  • Reproductions
  • Industrial Parts
  • Automotive Parts

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.

A test pour of the resin.

A test pour of the resin shows me just how hard and tough the material is. I poured a thin puddle of resin approximately 3/32” thick and let it cure for five days. This resin is really tough and rigid.
I see it should be degassed though. There are hundreds of very fine air bubbles trapped inside. I also think my resin was a little too warm when I mixed it and perhaps the working time was shorter than typical
Good resin.
