Why Use Zeolite Molecular Sieve in Your Polyaspartic Formula ?

Introduction

In this article we are going to explain why you need to use SUPERSIV^® Zeolite Molecular Sieve in your Polyaspartic Formula, if you want to make a good quality product.

To make things easy for you, we will take things step-by-step, and we will discuss the topic via a series of basic questions:

What Are Polyaspartic Systems?

Polyaspartic systems refer to fast-curing, high-performance resin coatings systems widely used in industrial applications (e.g. floor coverings, bridges, and protective finishes). This quick curing allows for faster return-to-service of the item that’s being coated, compared to other alternatives, such as epoxy systems.

Are Polyaspartic Systems Vulnerable to Moisture?

Polyaspartic coatings are based on aliphatic polyurea chemistry, and they are highly sensitive to moisture due to their reactive components, such as isocyanates and amines. Even trace amounts of water (from the atmosphere, substrate, polyol additives, pigments, or fillers) can react with isocyanates, to produce carbon dioxide (CO₂) gas, leading to defects like bubbles, pinholes, blisters, , or viscosity instability during storage.

To prevent this problem, zeolite molecular sieves, such as 3A SUPERSIV Powder are incorporated as precision moisture scavengers. These porous aluminosilicates selectively adsorb water molecules into their structure, trapping them and preventing unwanted reactions without affecting larger molecules like solvents or resins.

This is especially critical in 100% solids polyaspartic formulations, where products like pre-dispersed sieves (e.g. 3A SUPERSIV Paste ) ensure seamless integration and superior purity.

How much SUPERSIV should I use in my Polyaspartic Formula?

5 Reasons to Use SUPERSIV in your Polyaspartic Formula

1. Selective and Precise Moisture Control: The 3Å pores target only water vapor, ignoring larger formulation components, which minimizes interference and ensures targeted protection, even at ultra-low humidity levels.

2. Defect Prevention and Enhanced Finish: Eliminates moisture-induced issues like bubbling, down-glossing, and surface imperfections, resulting in smooth, uniform, bubble-free coatings with flawless aesthetics and durability.

3. Improved Stability and Shelf Life: Boosts chemical and thermal stability, preventing degradation during manufacturing, storage, or transport, which is vital for reactive polyaspartic systems.

4. High Adsorption Capacity and Versatility: Offers superior efficiency compared to other desiccants, works across a wide temperature range, and supports broader environmental application conditions without compromising performance.

5. Easy Incorporation: Disperses uniformly with minimal impact on colour or rheology, and can be supplied as a pre-dispersed in carriers for dust-free handling (see: 3A SUPERSIV Paste for more info).
