 CAS: 36290-04-7

 SLI SNF is high range concrete water reducer without air entraining component

It complies with chemical admixture specifications for concrete: ASTM C 494, type F; ASTM C 1017

 Sodium naphthalene formaldehyde is also called naphthalene based superplasticizer, poly naphthalene sulfonate formaldehyde, snf powder, pns powder, FDN powder, NSF, naphthalene high range water reducer, SNF superplasticizer. NSF powder, naphthalene formaldehyde, sodium naphthalene sulfonate, naphthalene sulfonate salt, superplasticiser

 Appearance: Brown powder

 Main Performance:

Sodium Naphthalene Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. Sodium naphthalene formaldehyde also allows concrete to be produced with very low water/cement ratios at low or normal slumps. Sodium Naphthalene Formaldehydeis ideal for use in prestress, precast, bridge deck or any other concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation

 Sodium Naphthalene Formaldehyde can be added directly or added in after dissolved. It can be added during mixing and after-mixing. The afterward approach can achieve better result. The suggested addition rate is 0.75%.

 Direction:  Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%). The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.
