Animal glue comes in cake form and is melted prior to use at different temperatures depending on the application. This glue is considered to be an eco-adhesive because it is totally non-toxic and biodegradable. This is possible because of the raw materials used to manufacture this glue.
Animal glue raw materials are as follows:
- Prior to 1970, mostly extracted from the bones and hides of pigs and cattle.
- Since 1970, majority comes from pharmaceutical scrap gelatin
- Soft gel netting and hard capsule gelatin are both used in glue manufacturing
- Soft capsule gelatin is sorted by color before use in animal glue manufacture.
- Further helps the environment by recycling pharmaceutical scrap that would otherwise be thrown in landfills.
- Animal glue is technically a water-based adhesive
- LD Davis only manufactures water-based adhesives in-house, whether they are animal glue or liquid glue.
- Also known as magnesium sulfate- made up of magnesium, sulfur, and oxygen.
- Epsom salts are also used in agriculture, medical applications, bath salts, and even in some food processing.
- Epsom salts are used in animal glue manufacture to add tackiness to the formula.
- Used in animal glue production for additional open time and wet tack.
- Derived from corn starch
- All natural sugar used in animal glue production
- Increases eco-friendliness because it is a renewable resource
- Used in animal glue production to add flexibility and non-warp properties.
- Colorless and odorless
- Used in pharmaceutical applications, is usually an ingredient found in soaps.
- Can be used as a food preservative and is often found in products like butter and margarine.
