About our product range
Samrat Poly Resins manufactures polyester resins at Doraha, Ludhiana: general-purpose and lamination grades, gelcoats, and fire-retardant and isophthalic grades. We also manufacture epoxy resins and supply the hardeners, glass fibre, pigments and workshop consumables used alongside them.
That is 51 products in all, and every one publishes a data sheet: 50 a Technical Data Sheet and one — Paint Brushes, an article rather than a formulated material — a Product Data Sheet. 23 also publish a Safety Data Sheet. Each product page shows exactly what is published for that product, and nothing is implied where a document does not exist.
