Spreaders and Penetrants

BREAK-THRU® - Technology for Agriculture


Both BREAK-THRU® Spreaders and Penetrants decrease the surface tension of pesticide formulations and thereby reduce the tendency of spray droplets to bounce off plant foliage. This effect allows for better deposition and retention on plant surfaces and maximizes the performance of agricultural chemicals. 


The BREAK-THRU® portfolio of Spreaders and Penetrants includes siloxane based polyethers and more recently biodegradable trisiloxanes and biobased polyglycerolesters. 

Due to their ultra low static surface tensions, BREAK-THRU® Spreaders provide superior spray coverage. They are unique among surfactants in their ability to impart phenomenal spreading characteristics to formulations. These products can also be instrumental in enabling cuticular penetration and in some cases stomatal flooding. As a consequence these surfactants help reduce the spray volume required for a particular pesticide application, and they allow for better targeting and increased pesticide uptake. 

While organo modified siloxanes are synonymous with super spreadering, Evonik has designed variants of this chemistry to produce similar static surface tensions without appreciable spreading to perform mainly as a penetrant. Quick penetration can translate into rainfastness in the case of many systemic pesticides as the delivery of the pesticide into the plant has been accelerated and a later rainfall cannot wash it from the plant’s surface. 

BREAK-THRU® SP stands for Sticker Penetrant. The BREAK-THRU® SP products improve the deposition and retention of the agrochemical sprays and facilitate the uptake of the pesticide. At the same time they meet today´s requirements for product safety, environmentally friendliness and convenience of handling. BREAK-THRU® SP products are outstanding with reference to their low foam tendencies.

  • BREAK-THRU® S 240
    The animated filmsequence shows the super spreading of a water droplet containing BREAK-THRU® S 240 versus an untreated droplet on polypropylene.

  • Aphid‘s escape from a water droplet  
    An aphid is stuck in a water droplet but wriggles its way out. 

  • Complete wetting of aphids with BREAK-THRU® S 240
    When the super spreader is added to the spray water, complete coverage of aphids can be achieved leading to much better contact with an insecticide.

BREAK-THRU S 240 is a non-ionic surfactant and belongs to the chemical class of organomodified  trisiloxanes. These are the only agricultural adjuvants that can produce a phenomenon known as “super spreading“ i.e. the rapid coverage of hydrophobic surfaces such as leaves at concentrations of 0.1 % or less.
