Progiline Allyl PAGs for the paint additive industry
Allyl Polyethers (Allyls PAGs) are a range of reactive chemical intermediates which predominantly find application in the manufacture of silicone polyethers.
Shrieve offer a wide range of these Allyl PAG reactive intermediates to the paint additive industry, where they are widely used to modify the properties of silicone based components.
Shrieve’s broad product range allows the additive manufacturer full scope to optimise the technical properties of the paint additive such as the rheological and levelling functions.
In addition to the paint additive industry, further silicone polyether applications include antifoams/defoaming agents, rigid and soft polyurethane foam stabilizers, and cosmetics/toiletries components.
Shrieve’s product range represents the diversity of the structural variations of the polyether component which may be required to produce specific silicone polyethers.
How Shrieve's Progiline ALLYL PAG product range is manufactured
Shrieve's Progiline ALLYL PAG product range is manufactured to incorporate a single reactive double bond functionality in the form of an allyl group (H2C=CH−CH2-) onto the end of the polyether polymer chain. The allyl polyethers are then reacted with silicon compounds to obtain polyether modified siloxanes. In this Platinum-catalyzed hydrosilylation reaction the allylic C=C bond of the functional polyether is reacted with the Si-H bond of the silicon compound to produce polyether modified siloxanes (“silicone polyethers”).
Primary benefits of Shrieve's Progiline Allyl PAG
- Greatly enhanced and controllable hydrophilicity improvements to silicones.
- Significant biocompatibility improvements to silicones.
- Highly controllable paint additive property modification due to Allyl Pag structural variations available.
- Shrieve capability to custom manufacture required Allyl Polyether molecules, including oxide type variations and terminating molecule variations.
- Lowest impurity contents and tightest product specifications achievable.
Shrieve’s expertise in partnering with customers enables us to offer an invaluable “custom” manufacturing option, our existing product range represents a broad spectrum of structural types utilised in applications today, but we can also offer the customer great flexibility in tailoring their Allyl Polyether to the specific structural requirement required for specific reacted silicone polyethers.

Typical structural variations encompassed by the Shrieve Progiline Allyl PAG product line include:
- Extensive molecular weight range available (ie. Polyether chain length), the typical range is 200- 1500 g/mol.
- Ratio of ethylene oxide/propylene oxide : ranging from fully hydrophilic (100% Ethylene oxide) to entirely hydrophobic (100% Propylene Oxide).
- Arrangement of Ethylene oxide & propylene oxide in the polymer chain : both random and block variations available.
- Terminating end-group : a full range of both hydroxy and methoxy terminated allyl polyether products are available.
