Curran® Granules

1 of 3 products in this brand
Curran® Granules is a performance additive, based on novel fiber technology and derived from root crops, provides a unique set of properties for water based coatings. High technical performance combined with the renewable nature of Curran®, helps solve many of the challenges faced by the paints & coatings industry today. Curran® is both green and multifunctional; using it as a film enhancer provides improved crack resistance and reduces film defects. It can also provide improved opacity and in some cases extended open time. There can be other benefits, such as enabling solvent reduction. With careful formulating, Curran® can bring improved performance and result in cost savings. Curran® also retains stability in a wide range of pH levels to make formulating easier .

Curran® Granules - Key Properties

 

Process Guidelines

Curran® Granules should be added at the dispersion/grind phase, ensuring there is sufficient water present for dispersion and rehydration (most common formulae will have sufficient water). For further information please request a copy of our incorporation video.

Addition Levels

Recommended addition levels of Curran® Granules are between 1-3% (based on supplied form), optimum levels are determined through a series of laboratory tests. The ratios of Curran® to HEC may be altered for optimisation depending on the required key properties of the formulation.

Packaging & Availability

Packaging Type

Storage & Handling

Storage Conditions

Store protection from frost and not above 40 °C. Opened containers must be closed again well since the product tends to form a skin.

Handling & Storage

 

Before using this product please consult the Material Safety Data Sheet (MSDS) for information on safe handling and storage. Recommended storage conditions are a cool and dry environment. Once open, containers containing Curran® Granules should be re-sealed to avoid moisture loss. Commercially, Curran® is supplied in 15 Kg boxes .
