It is prized across industries for its exceptional combination of strong adhesion, optical clarity, flexibility, and film-forming properties — all in one material.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003ePVB B03HX is a low-viscosity grade well suited to coatings, inks, and adhesive formulations where solubility and film performance are key. It dissolves readily in alcohols, ketones, and esters, and is highly compatible with a wide range of plasticizers and resins including phenolic, epoxy, and alkyd systems. The resulting films offer excellent toughness, gloss, abrasion resistance, and good water and oil resistance.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTypical applications include wash primers, metal and wood coatings, printing inks (including food packaging inks, as pure PVB is non-toxic), foil and vacuum metallisation coatings, ceramic binders, and adhesives for glass, metal, plastic, and leather substrates. It can also be cross-linked with thermosetting resins to boost chemical, solvent, and water resistance where durability demands are higher.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eRecommended usage rates for PVB B03HX vary depending on the application and solvent system. In coatings and primers, PVB resin is typically used at 10–30% of the total formulation, while ink formulations often call for lower loadings of around 5–15%. In adhesive applications, concentrations will depend on the substrate and desired bond strength, and are commonly used in combination with plasticisers to achieve the required flexibility and tack.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"My Skin Recipes","offers":[{"title":"500g","offer_id":51856371122456,"sku":"POLYVINYLBUTYRAL-500GM","price":133.35,"currency_code":"NZD","in_stock":false},{"title":"1kg","offer_id":51856371155224,"sku":"POLYVINYLBUTYRAL-1KG","price":235.75,"currency_code":"NZD","in_stock":false},{"title":"5kg","offer_id":51856371187992,"sku":"POLYVINYLBUTYRAL-5KG","price":1050.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0694\/1773\/0328\/files\/PEG150stearate.webp?v=1703818109","url":"https:\/\/thesourcery.co.nz\/products\/polyvinyl-butyral","provider":"The Sourcery","version":"1.0","type":"link"}
