Description
Introduction
RotoChem is a moisture-trapping additive designed specifically for rotational moulding, used in combination with RotoAid . While RotoAid works as a nucleating and lubricating agent, RotoChem handles the moisture side of the equation — trapping moisture from recycled polymer, reducing pinholes, and improving the shine of roto moulded tanks.
Together, RotoChem and RotoAid form a complete two-product system for defect-free water tank manufacturing.
Key Benefits
- RotoChem traps moisture from recycled polymer, enabling higher recycled content without moisture defects.
- It reduces pinholes by tackling the moisture that is the root cause of pinhole formation.
- It improves shine, giving roto moulded tanks a brighter, more premium finish.
- It contributes 100% of its weight to the polymer matrix, becoming part of the finished tank and supporting batch economics.
- It works in combination with RotoAid, completing a two-product defect-reduction system.
- Its moisture-protected 1 kg unit packs keep unused product sealed and fully effective until needed.

FAQ
What is RotoChem?
RotoChem is a moisture-trapping additive used in rotational moulding. It is used in combination with RotoAid to remove moisture and improve shine in roto moulded tanks.
How does RotoChem reduce pinholes?
Pinholes in roto moulded tanks are often caused by moisture turning to vapour during moulding. RotoChem traps that moisture — particularly the moisture carried by recycled polymer — before it can convert to vapour and create defects.
What is the recommended dosage of RotoChem?
The recommended dosage is 0.25% to 1% of the total batch size, depending on the colour and polymer being used.
When should RotoChem be added to the process?
RotoChem is added during the mid-cycle of dry blending the polymer, in combination with RotoAid .
Is RotoChem used alone or with another product?
RotoChem is used in combination with RotoAid . RotoChem handles moisture removal, while RotoAid acts as a nucleating and lubricating agent — together they form a complete pinhole-reduction system.
Does RotoChem improve tank surface finish?
Yes. RotoChem is used to improve shine in roto moulded tanks.
What does “100% weight to the polymer matrix” mean?
It means RotoChem does not burn off or evaporate during processing — every gram added becomes part of the finished tank, which supports batch weight and economics.
Why is RotoChem packed in 1 kg unit packs?
RotoChem is moisture-sensitive. The 1 kg unit packs (inside 25 kg bags) let you open only what you need, keeping the rest sealed and protected from humidity until use.
How should RotoChem be stored?
RotoChem should be stored in normal, dry conditions — away from humidity and moisture — to preserve its moisture-trapping effectiveness.
What is the difference between RotoChem and RotoAid?
RotoChem is a moisture-trapping additive that removes moisture and improves shine. RotoAid is a nucleating and lubricating agent that improves polymer mixing and finishing. They are designed to be used together as a complete system for reducing pinholes in roto moulded tanks.
Is RotoChem manufactured in India?
Yes. RotoChem is manufactured in India by Vin Group, an ISO 9001:2015 certified plastic and rubber additive manufacturer operating since 1997.
