- Reactivity
- Dynasylan® 1505 is a bifunctional organic compound in which the silicon-functional ethoxy-groups hydrolyze in the presence of water to form reactive silanols, which can be bonded to an inorganic substrate; the organophilic amino group can interact with a suitable polymer.
- The hydrolysis of Dynasylan® 1505 takes place autocatalytically in about 5-10 minutes.
- Hydrolysates having a concentration of < 5 wt.-% are stable for more than 72 hours.
- The pH is about 11.
- Examples of suitable inorganic substrates are: sand, mineral wool, silicic acid, quartz, cristobalit, wollastonite and mica; also suitable are aluminum hydroxide, kaolin, other silicate fillers, metal oxides and metals.
- Examples of suitable polymers are: phenolic resins, furan resins, silicones and melamie resin. Dynasylan® 1505 can undergo reactions with ketones or esters. Silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates or carbamates. Product modifications are possible through co-condensation with polysiloxanes.

- Application Characteristics
Dynasylan® 1505 is an important additive in many applications.
For example it can be used as an additive in cold-curing phenolic and furan foundry resins to improve the flexural strength of sand/resin elements with very long shelf life of the resins.
Further examples are:
- Glass and metal primers.
- abrasives: as additive to phenolic resin binders.
- mineral-filled composites: for pretreatment of fillers and pigments or as additive.
- synthesis of functional silicones.
The most important effects which can be achieved by using Dynasylan® 1505 are:
- improvement in product properties, such as
- mechanical properties, for example flexural strength, tensile strength, impact strength and modulus of elasticity.
- moisture and corrosion resistance.
Improvement in processing properties, such as
- adhesion.
